cLosUnE SEAL.

Application filed May 5, 1922, Serial No. 558,688. Renewed May 16, 1925.

To all whom it may concern:

'Be it known that I, EUGENE W. ZIPF, a citizen of the United States,residing at Mineral Ridge, in the county of Trumbull and State of Ohio,have invented a certain new and useful Improvement in a Closure Seal, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings.

This invention relates to seals for con tainers and includes also'amethod of sealing containers, such as barrels, tubes, and the like.

One of the methods heretofore employed for sealing barrels, particularlythose adapted for containing liquid material has embodied the use of aplug which is thread.- ed into a Wall of a receptacle or barrel, and isprovided with an opening through which the customary wire of a car sealmay be threaded. In shipment, however, such seals are frequently brokenwhenever the barrels are stored one above another; and in addition, theposition of the opening in the removable member with relation to that ofthe stationary member is not always bestfor convenient application ofthe car seal.

One of the objects of my invention, therefore, is theprovision of a sealwhich not only insures ample protection to the consignee, againstsurreptitious or unauthorized o ening of the container, but also*permits tile storage of one container above another without damage tothe seal.

My invention includes not only the seal, but also the method ofattaching the seal, as' will be hereinafter. described in connectionwith the drawings forming a part hereof., The essential features willbe, summarized in the claims.

In the drawings, Fig. 1 is a plan view of a closure member adapted foruse with my invention; Fig. 2 is a similar view showing a seal for theclosure; Fig. 3 is a vertical r section taken transversely through theclosure and container as shown in Fig. 2.

My invention is particularly well adapted for use on barrels or steelcontainers which are used for holding oil or other liquid material, andaccordingly, I have shown a portion of such container at 10. The wall ofthe container may be provided with an annular member 11 which may bethreaded, as at 12. to receive a plug 13.

strip which may have the name of the consignee stamped therein, ifdesired. This strip is shown as having an opening at each end thereoffor engaging the upstanding portions 21 on opposite sides of the flange14. The upstanding portions are adapted to be riveted over the strip,for securely holding it in place after it is extended over the closure.In this Way,.the strip is in close fitting engagement with the closure,and is thus protected against inadvertent displacement by contact withanother container or other object while in transit. The upstandingportions are preferably formed integral with the annular member 11.

From the foregoing description, it will be seen that a seal constructedaccording to my invention may be quickly attached to a container, and bepermanently held thereon even though subjected to the-usual roughhandling incident to shipments of this character. Since the strip liesflat against the closure and is somewhat flexible, it may be bent incontact with another object, but

the manner of attachment is such that there I is very little tendencyfor such contact to strip the seal from the container. Furthermore, theconstruction employed enables the seal to be attached to all forms ofcontainers without necessitating expensive construction which tends toincrease the cost ofmanufacture.

Having thus described my invention, Iv

claim:

1. In combination, a container having a threaded opening therein, athreaded closure in engagement with the opening, a strip of metalextending across the top of the closure, members extending upwardly fromthe container on each side of the closure and projecting through saidstrip, said members being permanently attached to the strip whereby theturning of said closure automaticall ruptures said strip.

2. In com ination. a container, an annular member rigidly securedthereto, said member having a flanged portion extending around theperiphery thereof, and having a threaded opening adjacent the centralportion thereof, a closure for said opening, a pair of upstandingportions on opposite sidesof said flanged portion, and a strip of lightsheet metal extending across the closure and having the ends thereofpermanently attached to said upstanding por- 10 tions, whereby turningof said closure automatically ruptures said strip.

In testimony whereof, I hereunto affix my signature.

EUGENE W. ZIPF.
